Definitions

  • the invention relates to a method fastening construction components in a casing for series-produced finished parts. More particularly the invention relates to a method of temporary fastening of a component sealed off against concrete infiltration in a casing for finished parts, primarily for prestressed-concrete cross ties, whereby a component provided at least indirectly with a central bore is fastened to the inside of the casing by a temporary connection means passing through this bore and through a bore determining the position of the component in a casing plate.
  • switch cross ties for the insertion of the component, e.g. tube sockets for the rail
  • fastening screws in the case of the switch cross ties--an accuracy is required which greatly exceeds that otherwise necessary for construction components. It is an important condition that the component can be fixed in the casing without being displaced during the pouring of the concrete, that the finished part can be removed from the casing, and that the cost of the required steps is low.
  • the connection of the component with the casing has to be shearable, in order not to impede the movements occurring between the finished part and the casing during the hardening process of the concrete and not to cause damage to the finished part or to the component.
  • a fastening method is known from German open application 36 29 030 (see also U.S. Pat. No. 4,948,089).
  • This open application further describes various types of fastening devices, consisting basically of a pin and a fastening nipple.
  • the nipple holds the pin in a bore in the casing plate, which determines the position of the component within the finished part.
  • the hollow pin and the nipple can assume various shapes which sometimes are very complicated and thus expensive, shapes.
  • the nipples can be built into the casing only from the less accessible bottom side.
  • the object is achieved in that a blind rivet which can be inserted and hammered in from above is used as a temporary connection means.
  • the rivet is pushed with its stem from above through the bore into a bottom plate indirectly or directly carrying the component as well as through the therewith aligned bore in the casing plate, until the rivet head stops against the bottom plate, up to the point where the lower edge of the component comes to lie flush against the casing plate.
  • the drawing mandrel is then pulled and simultaneously the pull head is pressed into the stem and with the simultaneous deformation of the stem to a rivet-head-like enlargement is solidly anchored on the outside of the casing plate.
  • the preselected breaking point of the drawing mandrel is provided inside the casing plate, suitably immediately behind the pull head.
  • the wall thickness of the stem of the blind rivet is so selected that the blind rivet is sheared off at the occurrence of a shearing stress of a small but definable value, between the correspondingly resistant bottom plate and casing plate.
  • Components to be fastened by the method of the invention can use a blind rivet which can be tightly attached to the casing plate by means of a loose bottom plate provided with a central bore which, with a contact surface, overlaps the projections formed at the bottom edge of the component.
  • the lower frontal surface of the component can be tightly pressed against the casing plate by the blind rivet, by keeping the portion of the plate thickness surpassing the thickness of the contact surface of the bottom plate slightly lower in the middle than the thickness of the projections of the component, thereby creating a gap between the lower side of the bottom plate and the upper side of the casing plate.
  • preselected breaking points can be established.
  • the thin bottom plate with a central bore can be formed, through which the component can be tightly attached to the casing plate by the blind rivet.
  • the bottom plate of the component can be curved so that its concave side faces the casing plate.
  • the bottom plate of the component can be staggered upwardly by a small measure against the lower margin of the component.
  • the component can be made of a hard synthetic material, for instance PA6.6 with the addition of fibers.
  • the bottom plate can be curved so that its concave side faces the casing plate and that in the space created by staggering, between the lower side of the bottom plate and the lower frontal surface of the component, a metal plate with a central bore can be fitted.
  • the device can be made of medium hard synthetic material, for instance PE or PA.
  • the bottom plate can be expelled from the casing after the completion of the finished part, due to a preselected breaking line along its surrounding margin.
  • a ring concentrically surrounding the bore and made of a superhard material in comparison with the rest of the bottom plate can be built in.
  • a blind rivet for carrying out the method is so constructed that its stem has a preselected breaking point in the plane between the lower side of the bottom plate of the component and the upper side of the casing plate.
  • the advantage of the method according to the invention is that, instead of a special nipple part with a complicated construction, a blind rivet available in commerce is used for the temporary shearable fastening of the construction component to the casing.
  • the blind rivet normally devised for fixed connections, meets in a simple way all the requirements of a temporary fastening means of the component to the casing.
  • the blind rivet makes possible to set the required impact point of the connection means for the fastening of the component on the outside of the casing plate, starting from the inside of the casing.
  • the parts used in the production of switch cross ties are equipped with means allowing the riveting of the component to the casing. In any case, these means have to be removed, before the finished part is used. Furthermore, the rivet in the casing has to be sheared off with certainty. This is done by correspondingly selecting the material for those parts of the device insuring the shearing off of the blind rivet. These device parts can be made of plastic or metal. The loose bottom plate according is suitably also made of the same material.
  • FIGS. 1 and 2 are cross sectional views of a component to be fastened according to the method of the invention, in FIG. 1 showing assembly prior to the extraction of the drawing mandrel, and FIG. 2 in a state of use showing the state of device during the concreting of the finished part; after the extraction of the drawing mandrel,
  • FIG. 3 is a view similar to FIG. 1 according to another embodiment of the invention.
  • FIG. 4 is a similar view of another embodiment
  • FIG. 5 is a section through still another variant.
  • FIG. 6 is a section through a final embodiment.
  • the component 6 is held on the casing plate 1 through a plug 3, over which the component 6 is sealingly slid.
  • the bottom of the plug 3 has a central bore 5.
  • the stem 8 of a blind rivet 7 extends from the inside of the casing through the bore 2 and the bore 5 of the plug 3 (FIG. 1) which is aligned therewith.
  • the pull head 11 is pressed into the steam 8 of the blind rivet 7 and the stem 8 is reshaped into an outer rivet-head-like enlargement 9 on the casing plate 1.
  • the drawing mandrel 10 is extracted, until the pull head 11 after forming the enlargement 9, stops and catches in the opening of the bore 2 and ruptures at the preselected breaking point 32.
  • the connection between the plug 3 holding the part 6 and the casing plate 1 is made solely by the hollow shaft 8 of the blind rivet 7 anchored by the head and head-like enlargement 9, whose material and wall thickness can be selected so that it will be sheared off by shearing forces of a certain strength.
  • FIG. 3 a connection means for fastening the component 15 with the casing 1 is shown.
  • the aforedescribed blind rivet 7 extending through the bore 13 of the bottom plate 12 and the bore 2 of the bottom plate 1 connects the bottom plate 12, with its contact surface 14 overlapping the projections 16 formed on the lower edge of the component 15, to the casing plate 1.
  • the thickness of the bottom plate 12 is selected so that a gap 17 remains between the bottom side of the bottom plate 12 and the upper side of the casing plate 1, when the contact surface 14 comes to rest on the brackets of the component 15. This insures that due to its tensional force, the blind rivet 7 presses the component 15 tightly towards the casing plate 1.
  • the projections 16 have preselected breaking points 33, so that they can be removed easily.
  • FIGS. 4 to 6 show examples of solutions for the direct connection of component and casing plate by a blind rivet.
  • a curved bottom plate 19 is formed in one piece with the component 18.
  • the bottom plate 19 is reinforced by a ring 35 of high-strength material, when compared to the rest of the bottom plate.
  • FIG. 5 shows a component 21 having a plane bottom plate 22 formed in one piece with the component and stepped by a distance 23 with respect to the lower margin of the component.
  • the blind rivet 7 is driven through the central bore 24 of the bottom plate 22 and the bore 2 of the casing plate 1.
  • the stepped configuration makes possible a tight adherence of the component to the casing plate 1.
  • FIG. 6 A variant of the example according to FIG. 5 is shown in FIG. 6.
  • the bottom plate 26 formed in one piece is also stepped by a distance 28, but in addition thereto, it is also curved.
  • a metal plate 29 is fitted in the gap space.
  • the blind rivet 7 passes through the mutually aligned bores 27 of the bottom plate 26 and 30 of the metal plate 29, as well as the bore 2 of the casing plate 1.
  • the curvature of the bottom plate 26 insures a tight adherence of the component 25 to the casing plate 1.
  • FIG. 6 a preselected breaking line 31 surrounding the margin of the bottom plate 26 is shown, which facilitates the later separation of the bottom plate 26 from the component 25.
  • a preselected breaking line can be provided in all components wherein the bottom plates are formed as parts thereof.
  • a preselected breaking point 34 of the stem 8 of the blind rivet 7 can be seen. This preselected breaking point is meant to facilitate the shearing-off of the rivet in the preestablished shearing plane.
